I've just fitted several new rads. Three of them were weeping. I drained down and fitted fresh PTFE tape and all but one of them is now fine.

The problem one is reusing the old copper pipes to the rads and I left the old olives in place. If the weeping is slight, will they seal themselves or should I tighten up harder or must new olives be fitted? I really don't want to damage the pipes and have to replace them as access is very tricky. New carpet being laid next Weds so I need to sort this by then.

if it saves me 15-20 quid on a tool. then every time i get the 20-30 pence olive off using my normal tools, then yes im happy as hapy can be.until my boss gives me money for tools then ill keep doing it the old way.p.s by the way softus i wasnt takin the p%^s about the soldering iron, you can actually buy them

In that case you should throw away all your tools except for a hacksaw, a hammer and a big screwdriver, because you could saw off every nut you find and do the new ones up by hitting them. That would be a big saving.

My olive cutters have easily paid for themselves by saving time that I've turned into more earnings by being able to do more jobs in a day.

not arguing on this one, depends on the person, im always arguing with fellow tradesman on the subject if bending pipe is quicker than soldering and i cant understand how soldering is better or quicker. each to there own, its funny how different tradesperson have there own views on different tools or different ways.
